Someone's plush collection. They have the Japan "Pale Sonic" and some bendies, but the notable thing in the picture is the Sonic who is wearing the tiny "Sonic & Knuckles" symbol shirt. Not many plushes were produced in the "Sonic & Knuckles" era, despite the greatness of the game.
A collector's doll shelf. This has a nice mix of new and old plushes. The Big the Cat and Chao were available through mail order from Japan when Sonic Adventure 1 came out. They were fairly reasonably priced then, but fetch huge prices on Ebay Auctions now.
